Question

1 multiple choice 1 point which of the following is the null hypothesis for a two sample t test? one of the differences between the means of the two groups being compared is smaller one of the differences between the means of the two groups being compared is larger here is a significant difference between the means of the two groups being compared here is no significant difference between the means of the two groups being compared

Explanation:

In a two - sample t - test, the null hypothesis ($H_0$) assumes that there is no significant difference between the population means of the two groups being compared. It is the hypothesis of no effect or no difference. The other options are incorrect as they do not represent the core idea of the null hypothesis for a two - sample t - test. The first two options talk about one of the differences (which is not the null hypothesis concept) and the third option is actually the alternative hypothesis in many cases (a statement of a difference).

Answer:

There is no significant difference between the means of the two groups being compared.
